CHAPTER XII.

THE METRIC SYSTEM OF WEIGHTS AND MEASURES.

158. The metric system of weights and measures, which was first introduced by the French towards

the close of the last century, has now been adopted by most of the Continental states of Europe. It is not yet introduced into England, though its permissive use was legalised by an Act of Parliament passed in 1864, but it is not unlikely that further action will ere long be taken by the Legislature, with a view to its complete adoption.

159. This system takes its name from the metre, or unit of length, which is the ten-millionth part of the distance from the pole to the equator, and from which all the other measures and weights are derived.

160. The several denominations of the metric weights and measures are connected by a uniform decimal scale, the tens, hundreds, thousands, and ten-thousands of the scale being denoted by the Greek words deka, hecto, kilo, myria; whilst the tenths, hundredths, and thousandths are denoted by the Latin words deci, centi, milli.

161. These Greek and Latin numerals are called prefixes, being prefixed or placed before the principal units of the several weights and measures, to express their multiples and divisors.

162. The following is a table of the metric prefixes, with their equivalent decimal values :
